Malware and other types of cyber threats have key target platforms or operating systems and these depend on the number of potential victims that they can penetrate. That said, we can assume that cybercriminals look at platforms and OSes that are popular or have the most number of users.



Microsoft’s Windows operating system has long been a popular target among cybercriminals not only because of the number of people running on the platform but also because most crucial industries operate on Windows. Windows remains one of the most popular OSes with 35.29% market share.



Apple’s macOS has only 8.07% share in the market but the platform has been increasingly becoming a favored target among cybercriminals because of its users. Knowing that macOS devices like MacBook laptops and iMac desktops are expensive, cybercriminals know that users of these devices have thick wallets. Another factor why cybercriminals target macOS is its association to Apple’s mobile platform, iOS.

Things To Look For When Choosing An Internet Security Suite

Internet security suite, given its array of features, can be considered as the best type of Internet security solution for both consumers and businesses. Instead of purchasing Internet security features individually, picking an Internet security suite makes sure that you get a better set of preventive measures against cyber threats.

Most Internet security suites are initially offered as trial versions. But once you are about to make a decision, what are the factors that you should consider when choosing an Internet security suite? Let’s take a quick look.

Real-Time Protection

Your Internet security software must perform scheduled scans to search for malicious apps you might have downloaded and running on your device. Look for the one that notifies you as soon as possible threats emerge.

Device Compatibility

Some Internet security solutions are incompatible with some operating systems. Make sure that the software suite you’re buying will install and run on your device without any issue.

Encryption Technologies

One example is a virtual private network (VPN). Some Internet security software have this to hide you from cybercriminals when you are online. A VPN masks your identity and location to protect you from any threats.

DNS Protection

DNS hijacking happens when an inauthentic website lures you to visit it instead of the authentic ones. Look for Internet security solutions with DNS protection so you know you’re safe fraudulent websites.

Webcam Protection

Camfecting has become more prevalent these days and while the cybercriminals behind this threat do not attempt to get your bank info, they go after your privacy and capture intimate footage for their pleasure.


Make sure that your Internet security software has an anti-phishing feature that can identify phishing content in emails and websites. This feature warns you when you are about to disclose information to threats.

Ongoing Support

You might encounter an issue or have a question about your Internet security solution. Make sure that the company behind it offers aftersales support as some will just leave you behind after you pay.


Evaluate the prices offered. Some Internet security software will be cheaper than others but will ask you to shell out extra bucks if you want to add or keep some additional features for added security.
